Description

  The present invention relates to an anti-condensation material for an indoor wall surface of a building structure, particularly a wall surface such as an entrance or an indoor door, a glass window, or a wall. More specifically, the present invention relates to a dew condensation preventing material including a heat insulating layer provided so as to cover an indoor wall surface of a building structure, and a cavity surrounded by the heat insulating layer.

  Architectural structures, especially buildings and condominiums, are more airtight than ordinary dwellings, and because the air-conditioner keeps the indoor temperature almost constant, the temperature in winter and outside temperature (for example, about 4-5 ° C) The difference from the room temperature (about 20 ° C) is large. The door of the entrance exposed to the outside air is made of a steel plate having good heat conductivity (that is, the heat conductivity is 39 kcal / mh ° C.), and the heat conductivity of the window glass is relatively 1.9 kcal / mh ° C. Good. Therefore, it is considered that the surface temperature of the door or window glass directly exposed to the outside air on the indoor side is substantially equal to the outside air temperature. For this reason, moisture in the air condenses when indoor air comes into contact with indoor surfaces such as doors, windowpanes, and walls with insufficient heat insulation, and dew condensation occurs.

  Calcium chloride, silica gel, charcoal, and the like are generally commercialized and widely used as a measure for removing moisture in a room and moisture during a rainy season.

  In addition, as a device for preventing dew condensation occurring on a door or a window glass, a device in which a sheet heating element is attached to wallpaper, and the sheet heating element is energized to generate heat and heat a wall has been proposed ( For example, see Patent Documents 1 and 2.

  Further, a dew condensation preventing material in which a release paper is provided on one surface of a heat insulating material made of a foam, a felt, or the like via an adhesive has been proposed (for example, see Patent Document 3).

  In the case of the dew condensation preventing materials disclosed in Patent Documents 1 and 2, both have a sheet heating element and generate heat when energized. Therefore, a temperature control mechanism and a leakage prevention mechanism must be provided. Must.

  Further, in the case of the dew condensation preventing material disclosed in Patent Document 3, there is a problem that the heat insulating effect is not sufficient because the thermal insulation depends only on a heat insulating material made of a foam, a felt or the like.

  The purpose of the present invention is to provide an anti-condensation material that has a simple structure that does not require electric equipment such as a sheet heating element, can achieve a heat insulation effect that cannot be obtained with conventional technology, and is also excellent as an interior design. It is to be.

Therefore, with a simple structure that does not require electrical equipment such as a sheet heating element, it is possible to achieve a heat insulating effect that cannot be obtained with the conventional technology, and to provide an excellent dew condensation preventing material as an interior design. it can.

  Thus, according to the anti-condensation material of the present invention, since it does not use chemical substances such as calcium chloride and silica gel, it is harmless even to young children, is easy to replace, and is simply left as it is. Removes moisture. Further, the anti-condensation material of the present invention is not limited to application to doors, windows, and walls, but can also be applied to closets, closets, and the removal of moisture from shoe boxes.

  The dew condensation preventing material of the present invention will be described in detail below with reference to the accompanying drawings.

  FIG. 1 is an explanatory view showing a state in which a frame of a dew condensation preventing material according to one embodiment of the present invention is attached to an indoor surface of a door, and FIG. 2 is a diagram showing a dew condensation preventing material according to one embodiment of the present invention. FIG. 3 is a cross-sectional explanatory view showing a dew condensation preventing material according to another embodiment of the present invention, FIG. 4 is a cross-sectional explanatory view showing a dew preventing material according to still another embodiment of the present invention, FIG. 5 is a front view showing a dew condensation preventing material according to still another embodiment of the present invention, FIG. 6 is an explanatory view showing a dew preventing material according to still another embodiment of the present invention, and FIG. FIG. 8 is an explanatory view showing a dew condensation preventing material according to still another embodiment, FIG. 8 is a side view of FIG. 7, FIG. 9 is an explanatory view showing a dew condensation preventing material according to still another embodiment of the present invention, and FIG. Explanatory drawing which shows the dew condensation preventing material concerning other embodiment of this invention. A.

  Referring to FIGS. 1 and 2, the anti-condensation member of the present embodiment includes a frame 1 (see FIG. 1) and a cover 2 (see FIG. 2), and the frame 1 and the cover 2 are insulated. Make up the layers.

  With reference to FIGS. 1 and 2, the frame 1 is composed of two wooden vertical members 1 a arranged in parallel, and between the two vertical members 1 a, with respect to the two vertical members 1 a. And six cross members 1b arranged in the vertical direction. In the present embodiment, the six horizontal members 1b are arranged at equal intervals and in parallel and parallel to each other, and the vertical members 1a and the horizontal members 1b are fixed to each other by a known fixing means such as a nail, a wood screw, or an adhesive. Is done. When the frame 1 is thus obtained, the cover 2 is fixed to the frame 1 by a known fixing means such as glue or an adhesive (see FIG. 2). It is important to fix the vertical member 1a and the horizontal member 1 with good airtightness in order to improve the airtightness of the recess described later. Therefore, if glue or glue is applied and then fixed using nails or wood screws, or if a groove is formed and glue or glue is applied and then fixed using nails or wood screws, a recess will result. It is effective to increase the airtightness of the airbag.

  When the frame 1 and the cover 2 are assembled, seven recesses 3 are formed by the frame 1 and the cover 2. As shown in FIG. 2, the anti-condensation material of the present embodiment is attached via an adhesive layer 4 to a facing surface of the frame W on which the coating 2 is not provided. When the anti-condensation member of the present invention is attached to the wall surface W, the recess 3 becomes a space closed by the wall surface W, the frame 1 and the cover 2. The closed space thus formed functions as an air layer. Since the thermal conductivity of air is as low as 0.021 kcal / mh ° C., the recess 3 effectively functions as a heat insulating layer. The recess 3 may be filled with one or more of glass wool, cotton or wool. The thermal conductivity of glass wool is 0.034 kcal / mh ° C, the thermal conductivity of cotton is 0.052 kcal / mh ° C, and the thermal conductivity of wool is 0.036 kcal / mh ° C. There is an advantage that condensation can be absorbed by capillarity.

  The number of cross members 1b is not limited to six as shown in FIGS. 1 and 2, and does not need to be arranged at equal intervals, and may be, for example, 2 to 5, or 7 or more. Similarly, the number of the vertical members 1a is not limited to two, and three or more can be provided. By providing a large number of the vertical members 1a and / or the horizontal members 1b, it is possible to realize the formation of a large number of isolated recesses 3. Providing a large number of recesses 3 is preferable because the space of each recess 3 becomes small, convection does not occur in the space, and the transfer of heat at a low temperature on the wall surface W is preferable. Therefore, as shown in FIG. 4, the case where only one recess 3 is provided is included in the present invention, but the space (volume) of the recess 3 is made as small as possible in order to prevent the generation of convection. Alternatively, it is preferable to fill the recess 3 with a thermal insulator such as glass wool or cotton.

  As a material of the frame 1 (that is, the vertical member 1a and the horizontal member 1b), for example, wood is suitably adopted. The reason is that the thermal conductivity is as small as 0.091 kcal / mh ° C., and the wood itself is a porous material, so that it has a certain degree of hygroscopicity and water retention. However, the material of the frame 1 is not limited to wood, and for example, a synthetic resin material such as styrene foam can be adopted.

  As the material of the cover 2, paper such as shoji paper, Japanese paper, or Western paper is suitably used. The reason is that, like the above-mentioned wood, the paper itself has thermal insulation, hygroscopicity and water retention.

  FIG. 3 shows a modification of the dew condensation preventing material of FIG. In the case of the dew condensation preventing material of FIG. 2, the attachment to the wall surface W of the frame 1 is performed by an adhesive or an adhesive 4, whereas in the case of the dew condensation preventing material of FIG. 3, a magnet (permanent magnet or electromagnet) is used. 5, the frame 1 is attached to the wall surface W. Therefore, the anti-condensation material shown in FIG. 3 is applied to a door manufactured from a ferromagnetic material such as a steel plate, and is not applied to a wall such as a window glass manufactured from a non-magnetic material such as a window glass. Absent.

  Referring to FIG. 1, a projection such as a knob L is usually attached to a wall surface W of a door. When there is such a protrusion, by providing the auxiliary member 1c made of the same material as the frame 1, only the region surrounded by the vertical member 1a, the two horizontal members 1b, and the auxiliary member 1c is provided. The coating 2 may be provided on other portions while leaving the coating. In a region including such a protrusion, the heat insulating layer does not exist on the wall surface W. However, even if dew condensation occurs in the region, the frame body 1 absorbs moisture.

  Referring to FIGS. 5 and 6, there is shown a dew condensation preventing material 10 covering a part of the wall surface W of the door. The dew condensation preventing material 10 shown in FIGS. 5 and 6 is also attached to the wall surface W with an adhesive or glue similarly to the above-described dew condensation preventing material, but as shown in FIG. If a magnet seal (magnet) is attached, it can be easily attached to the wall surface W of the iron plate door. Further, as shown in FIG. 6, if a paper or synthetic resin insert 8 connecting the four corners (corners) of the dew condensation preventing material 10 or the facing frames is provided, the frames are strongly reinforced. be able to. In addition, as shown in FIG. 5, if a sheet on which a replaceable illustration G is drawn is provided on the surface of the anti-condensation material 10, the user can provide an anti-condensation material that matches his / her room preference. Can be.

  7 and 8 show a dew condensation preventing material 10 which can be easily attached to a wall surface of a Western-style room or a Japanese-style room. For example, an L-shaped member 6 made of a synthetic resin and having an L-shaped cross section, which is sold in a do-it-yourself center or the like with a name such as a white angle (trade name) (a long section having an L-shaped cross section and extending in the longitudinal direction) 7 and 8 are formed into a frame having a frame shape in the left, right, up and down directions, and attached to the outer periphery of the dew condensation preventing material 10 with an adhesive or a fixing means such as a screw or a nail. Thereafter, the L-shaped member 6 is attached to the wall surface of a Western-style room or a Japanese-style room via an adhesive or a fixing means such as a screw or a nail.

  9 and 10, the dew condensation preventing member of the present invention may use a member 7 called a wiring cover (trade name) as the frame 1. The wiring cover (trade name) has a U-shaped member 7 having a U-shaped cross section as shown in FIG. 9 or a structure having a male part 7a and a female part 7b shown in FIG. However, both are applicable to the present invention.

  Hereinafter, the present invention will be described in more detail with reference to examples. The present invention is not limited to the embodiment.

Example 1
One anti-condensation material 10 shown in FIG. 6 was prepared. The vertical member 1a and the horizontal member 1b of the anti-condensation member 10 in FIG. 6 were both made of wood, and each side had a length of 1 meter. Shoji paper was used as the covering material. Further, a magnet was used as a means for fixing the dew condensation preventing material 10 to the wall surface.

  The dew condensation preventing material of the present invention was attached to a steel plate door under the conditions of an outside air temperature of 5 ° C., a humidity of 80% RH, and an indoor temperature of about 20 ° C. As a result, the moisture absorption per square meter was 150 g after one hour. In addition, the dew condensation preventing material that had absorbed the dew condensation returned to its original state (0 g of moisture absorption per square meter) after natural drying for about 2 to 3 hours.

Comparative Examples 1-3
An anti-condensation material was produced in the same manner as in Example 1, except that a polystyrene foam, a polyethylene film and a nylon film were used as the coating material. In the same manner as in Example 1, it was mounted on a steel plate door under the conditions of an outside air temperature of 5 ° C., a humidity of 80% RH and an indoor temperature of about 20 ° C. After 1 hour, the moisture absorption per square meter was 0 g, and the dew could not be sufficiently prevented.

  As described above, according to the dew-prevention material of the present invention, dew condensation occurring under conditions of 5 to 10 ° C. outside air temperature, 70 to 80% RH humidity, and indoor temperature of about 20 ° C. in winter can be effectively absorbed. found.

  Since metal such as iron, which is a material of the door, does not absorb moisture at all, moisture in the air is condensed by the moisture absorbing coating of the dew condensation preventing material. Therefore, aggregation of moisture on the door is suppressed, and dew condensation can be prevented. On the other hand, by leaving the moisture-absorbing dew-preventing material in a high-temperature or low-humidity state, the water condensed in the dew-preventing material is released into the air, and the dew-preventing material can be regenerated. If necessary, the use of ventilation fans and opening of doors and windows accelerates natural drying and shortens the time required to regenerate anti-condensation materials.
